ILOILO CITY — A recent study on land subsidence in metropolitan cities in the country showed that Iloilo City has recorded significant ground subsidence with rates reaching 9 millimeters (mm) per year.

The University of the Philippines study of 'Ground subsidence in major Philippine metropolitan cities from 2014 to 2020' said that land subsidence or the sinking of the ground surface 'has become a significant global issue caused by excessive groundwater extraction, rapid urbanization, and natural sediment compaction, exacerbated by climate change through rising sea levels.'
